We are Marfeel, one of the hottest European start-up companies, and we help publishers of all sizes to create, optimize and monetize their mobile websites. We have been named 16th fastest-growing European company of 2018, by The Financial Times, but we still think we have a long way to go to where we want to be.

We are looking for a Senior Frontend Engineer to join our Engineering department of over 70 talented developers, and become part of a Core Product team that is responsible for the architecture and the performance of our frontend ecosystem that supports over 700 million visits monthly. We obsess about performance and the quality of our code, and we are looking for like-minded developers to join us.

Our headquarters are based in sunny Barcelona and our office has a huge terrace to enjoy! 

As a Senior Front-end Developer at Marfeel you will:

- Deliver work on-time, accurately and most importantly in a robust way that doesn't degrade the quality of the code base

- Drive improvements in performance and architecture of the current Marfeel platform

- Join a fun and dynamic Core product team that follows Agile practices

- Have the opportunity and support to grow and develop your career further
